The dataurl parameters can be given any URL. Any "real data" that is returned (FITS images, ASCII tables, and various XML structures) will be saved in a cache and (if parameter immediate is true; the default) added to the current display. The dataurl references (0-9) must start with 0 and be contiguous. We stop at the first null (or 9).
